FFXIV Paladin Parity Core Changes

The important part here is the Enmity Fixes. If you want PLD to have AoE or to be able to Sword Oath tank, then so too is the Sword Oath revision. Shield Swipe buff adds MT dps. The combo adjustment synergizes with the rest to remove any possible threat issues and adds ~1-2% OT dps and up to triple mana regeneration for more support functionality.

I. Enmity Fixes

Shield Oath enmity modifier has been raised from 2.0 to 2.3, equal to Defiance and Grit.

Flash now also scales with Critical Strike. Flash potency has been decreased by 33% but now always counts as a critical strike.

Flash should now be able to keep up with Dark Knight AoE threat where needed or with Warrior if without Berserk, and should be able to compensate for CD unloading by AoE dps or make up for separate focus targets while Fight or Flight is up.

Not a huge increase to average AoE enmity, but now increases it according to the same factors all other tank AoE sources of enmity were already increased by, and should give it enough on command to suit its needs.

II. Combo Adjustments

Royal Authority's combo bonus can now be triggered by either Riot Blade or Savage Blade.

Up to triple the mana per GB, up to 60 more potency per GB (per 3 combos), and more enmity control as OT as not to rip hate from MT with the improved Savage Blade (meant to aid Sword Oath tanking)

This also gives PLD rotations at least something unique.

III. Shield Swipe Buff (CD Refreshable)

The cooldown of Shield Swipe may now be refreshed by blocks. Refresh chance varies with shield type (Bucklers-30%, Kite Shields-36%, Tower Shields-42%). Pacification increased from 6s to 8s.

This should provide a decent MT dps boost--about 20 more potency per second (up to about a 7% bonus in Shield Oath) if usage rate were tripled--and brings it a bit closer to DRK's Low Blow value for trash mitigation.

IV. Sword Oath Revised

Sword Oath - increases the potency of all weaponskills and abilities by 25, and causes weaponskills to cleave nearby enemies for 25% damage for 20% increased TP cost per enemy (to a maximum of +100% TP cost). Cannot be used with Shield Oath. Cleave component toggled on recast.[Cleave does not cause additional effects.]

This still equates to about a 13.4% ST dps increase [current version ranges ~10 to 15%], or up to nearly a 15% increase when combined with the new Riot-Royal combo option [about equal to a 2.0s sword with current Sword Oath]. Better synergy and significant improvements to Sword Oath tanking compared to the current version, while contributing nearly equal damage. Also gives PLD similar AoE dps to other jobs.

Also has the side-effects of:

increasing CoS burst by 25% and overall damage by 10%, [Note that the DoT component has no multiplier while the initial hit has a 3x multiplier, giving Sword Oath CoS 75 more enmity than its original (a 16.7% enmity bonus)]

smoothing rotational threat while in Sword Oath

making Royal Authority more usable and Rage of Halone more rewarding when tanking in Sword Oath
